Towards the construction of workflow-suitable conceptual modelling techniques

Despite their high-level and graphical nature, workkow speciications require a signii-cant amount of implementation detail-e.g. application programming interface, database access and programming mechanisms for information ow-for a more comprehensive validation than is currently possible. This is currently recognised as a deeciency in workkow conceptualisation. Although conceptual modelling techniques are available which are expressive , comprehensive and precise enough, we believe, their concepts and features are not specialised enough for workkow domains. In this paper, we ooer a comparative insight into techniques which characterise diierent aspects and approaches of workkow speciications. These are: structured process modelling, object-oriented modelling, behavioural process modelling and business-oriented modelling. In particular, we determine gaps for workkows capturing operational business transaction processing, e.g. those of insurance claims, bank loans and government-related registration. For technique construction, we describe ve workkow suitability principles.
